“…Here the slot is either placed on the patch or at the center point on the ground plane below the patch. Increment in the input impedance for the slot on patch is higher than the slot on ground plane [24]. The higher impedance will pose problems for the input impedance matching.…”

Wide bandwidth compact rectangular and equilateral triangular microstrip antennas employing slots cut bow-tie shape ground plane profile are proposed. Amongst all the designs, patch employing three rectangular slots cut bow-tie shape ground plane yields optimum results. Using the rectangular patch, against conventional ground plane design, increase in bandwidth by 20%, resonance frequency, substrate thickness, and patch area reduction by 32%, 0.034λ g , and 61.12%, are respectively achieved. In equilateral triangular patch design, a three rectangular slots cut bow-tie shape ground plane configuration shows bandwidth increase by 30%, and substrate thickness, fundamental mode frequency, and patch size reduction by 0.027λ g , 16.4%, and 36.28%, respectively. Proposed antennas exhibit radiation pattern in the broadside with a gain of more than 5 dBi.

“…To obtain maximum frequency reduction in the W-shape design, slots on the top horizontal edge are placed at l x = L/4, from the patch center. 14 An optimum design is realized by employing the parametric study for the increase in W s against the increase in BW, reduction in TM 10 mode frequency and reduction in the gain. The optimum design has the antenna parameters as, W s = 3.0, W gs = 2.1, L s = 0.5, l x = 2.1, h a = 2.4, h s = 2.3, X f = 3.0, W pf = L pf = 1.0 cm.…”

“…To realize reduction in the frequency, slot is embedded at the maximum current location of the fundamental mode on the patch or on the ground plane that lies exactly below the patch center. A slot on the ground plane provides optimum control of the input impedance at the fundamental mode with an equivalent amount of frequency reduction 14 . Hence, in this study ground plane slot is considered.…”

Proximity‐fed compact wideband rectangular and circular microstrip antennas by employing H‐shape, C‐shape, and W‐shape ground plane profiles are proposed. Optimum results are obtained in rectangular microstrip antenna using H‐shape ground plane. Against the conventional ground plane, it gives 16% bandwidth improvement, supported by 17.29% and 31% reduction in resonant mode frequency and patch area, respectively. The proposed design exhibits a broadside pattern with a gain of 6.1 dBi and can find applications in GSM 900 band.
